Structure of the Calystegines: New alkaloids of the nortropane family.

Structure of the Calystegines: New alkaloids of the nortropane family. Calystegines in Calystegia sepium derive from the tropane alkaloid pathway Identification and quantification of calystegines, polyhydroxyl nortropane alkaloids Calystegin N1, a novel nortropane alkaloid with a bridgehead amino group from Hyoscyamus niger: structure determination and glycosidase inhibitory activities Dihydroxynortropane alkaloids from calystegine-producing plants Sepaconitine — A new alkaloid from Aconitum septentrionale Calystegines as a new group of tropane alkaloids in Solanaceae N-acetylsepaconitine — A new alkaloid from Aconitum leucostomum Calystegins, a Novel Class of Alkaloid Glycosidase Inhibitors The isolation from Nicandra physalodes and identification of the 3-O-β-D-glucopyranoside of 1α,2β,3α,6α-tetrahydroxy-nor-tropane (Calystegine B1)
